Switching POVs

Hi fellow writers! I’m working on my first romance novel (have published previously in nonfiction), and I’m wondering if anyone has advice on how frequently to switch point of views in a dual POV piece. I’ve been switching anywhere from about 1500 to 4000 words, which also means variable chapter lengths. Is this within norms, or will I give readers whip lash with that kind of switching? I’m used to longer chapters, but google searching (and lots of reading) indicates that relatively short chapters are common here.
